Rolfs, he came to the conclusion that his species was identical 
with that from Florida, but that both were distinct from 
Sphaerostilbe coccophila Tul. He named his species Nectria 
coccophila, and gave the dimensions of the ascospores as 
15-20 x 5-6. It occurred on Asfidiotus perniciosus and 
Diaspis pentagona. 
In the same year, Zimmermann published an account of the 
fungi parasitic on scale insects in Java. He described a Nectria 
with a stilboid synnema, which he named Nectria coccido- 
phthora, distinguishing it from Nectria auranticola B. and Br. by 
its colour and the form of the synnemata. It occurred on 
Mytilaspis sp. and Parlatoria zizyp. In addition, Zimmermann 
recorded and figured Ophionectria coccicola, and described two 
other new species, Lisea Parlatoriae on Parlatoria zizypi, and 
Broomella Ichnaspidis on Ichnaspis filiform. 
In 1902, Hennings instituted a new genus Tetracrium for a 
conidial fungus found in company with scale insects on orange 
leaves, in Brazil, the species being named Tetracrium Aurantit. 
This specimen was re-examined by von Hohnel in Ig11, and 
found to be identical in structure with the conidial stage of 
Ophionectria coccicola. Von Hohnel also found on the type 
specimen perithecia which he regarded as belonging to the genus 
Putiemansia Henn.; he named these Puttemansia Auranti, and 
made corresponding alterations in the nomenclature of the 
North American species. 
In 1903 Hennings described a new species of Fusarium, 
Fusarium coccidicola, on a coccid on tea in German East Africa. 
In 1904, McAlpine added two new species of Mucrocera, 
Microcera tasmaniensis on Aspidiotus on Eucalyptus, and 
Microcera Mytilaspis on a scale on Hymenanthera dentata, and 
gave figures of both species. 
Parkin, in 1906, published a general account of the fungi 
parasitic on scale insects, and gave descriptions of a number of 
forms, collected in Ceylon and elsewhere. He referred the 
Ceylon Nectrias to Nectria coccidophthora, although there was 
a previous Ceylon record, viz. that of Nectria aurantiicola. The 
chief merit of his paper, as far as the present group is concerned, 
is that he recognised that there are two quite different conidial 
forms, appertaining to the Nectriae, common on scale insects 
in the tropics. But he assigned the Microcera form to Fusarium, 
and the other to Microcera. Parkin also refers to a Calonectria, 
found on Chionaspfis vitis and Mytilaspis citricola in Ceylon. 
In 1907, Trabut described Microcera Parlatoriae, found on 
Parlatoria zzyphi on orange at Algiers. 
In 1908, Fawcett summarised the records of “‘ Sphaerostilbe 
coccophila,”’ and gave details of its structure, in a paper en-
